Problems solved by technology
That is, in the above-mentioned publication, there is no consideration about the following situation that is a problem in the present invention: even if the air cylinder starts to operate normally, the full bobbin and the empty bobbin inserted on the peg plate transferred by the left and right transfer members are not considered. The quantity of the load fluctuates during the transfer, and the speed of the transfer member is changed to cause obstacles in the transfer of the bobbin

Embodiment Construction
[0020] Below, according to Figure 1A~ Figure 4C The first embodiment of the present invention will be described. As shown in FIG. 1A , on the left and right sides of the spinning frame 11 , first and second transfer devices T1 and T2 are arranged extending along the longitudinal direction of the spinning frame 11 . The 1st connection part 13 which transfers the peg plate 12 from the 1st transfer device T1 to the 2nd transfer device T2 is provided in the 1st end part side (gear end GE side) of the spinning machine frame 11. On the second end side (outer end OE side) of the spinning machine frame, there is provided a second connecting portion 14 for transferring the peg tray 12 from the end of the second transfer device T2 to the end of the first transfer device T1. Such as Figure 2B As shown, a circular locking recess 12 a is formed on the lower surface of the peg plate 12 , and a pin 12 b for mounting the bobbin B is protruded from the upper surface of the peg plate 12 . ...

A bobbin carrying apparatus in a fine spinning machine which is provided with first and second transporting devices (T1,T2), a connection portion for connecting the first and second transporting devices, first and second solenoid valves (32,33), and a control device (C) is disclosed. Each of the first and second transporting devices is provided with a peg tray path (16), a transporting member which can reciprocate so that peg trays are moved, and air cylinders for reciprocating the transporting members. The control device (C) controls the first and second solenoid valves (32,33) so that the point in time when the first air cylinder (21) starts operating is delayed relative to the point in time when the second air cylinder (22) starts operating.; The bobbin carrying apparatus is provided with first and second operating period sensing portions (S1a,S1b,S2a,S2b) for sensing the operating periods of the first and second air cylinders (21,22), respectively. The control device (C) corrects the difference in time when the first and second air cylinders (21,22) start operating in accordance with the fluctuation in the operating period as sensed by the two operating period sensing portionsso that peg trays on the first transporting device (T1) do not apply a pressing force to peg trays on the second transporting device (T2).
Description
technical field [0001] The present invention relates to a bobbin conveying device for a spinning machine, and more specifically, to a bobbin conveying device for a spinning machine that conveys an empty bobbin and a full bobbin by using a peg plate on which pegs protrude from the upper surface. Background technique [0002] In general, in an endless spinning machine, in order to facilitate the automatic replacement operation of the bobbin changing device, it is necessary to send out the full bobbin of doffing and arrange the empty bobbin along the spindle track in a state corresponding to the spindle pitch. Conventionally, there has been used a bobbin conveying device that conveys an empty bobbin and a full bobbin by using a peg plate on which a peg protrudes from the upper surface. In this device, the first and second transfer devices are extended on the left and right sides along the longitudinal direction of the lower portion of the spinning frame. A connecting portion c...
